Hybrid Cars the Energy Savers

By Brian Neil

If you are a car enthusiast you will be interested to know how a hybrid car works. They are the most viable answer found so far to the problem of high fuel prices. They basically have two power sources. One is an internal combustion engine that burns gasoline in order to power the vehicle. The other is a battery that could store electric power to run an electric motor that could power the automobile.

The biggest advantage with hybrid cars is that they are able to generate power with the kinetic energy it will otherwise waste during applying brakes and when the vehicle is going downhill. Though a normal automobile will burn fuel to power the breaks the hybrids will absorb the energy and store it in their batteries in order to use it when the vehicle needs power. Due to this reason, a hybrid car is able to provide much better mileage per gallon of fuel than regular automobiles.

There are two types of hybrid cars. One is called the parallel hybrid and the other is the series hybrid. In a parallel hybrid car both the engine and the battery driven motor are connected to the transmission. When the vehicle moves, both gasoline engine and the electric motor provide power. Due to this reason, most hybrids use smaller engines to make them low in weight. These do not need a special starter motors to start them as the electric motor is able to do that. When it comes to series hybrids their engines are connected to the generators and the generators are able to either drive the transmission in order to move the vehicle or to charge the batteries
A hybrid car uses several strategies to save power in order to emit cleaner emissions and to save money by using less fuel. When the car is stopped at a traffic signal, it doesn't need to run the engine. Therefore, the engine is shut off and only the electric motor will run. They also use lighter engines to reduce weight. The aero dynamic design is another way they save fuel. This will reduce the air resistance to a minimum.

Any hybrid car is made out of strong but light weight materials. This will reduce the overall weight of the automobile. Normally plastics, aluminium and carbon fiber are used. Almost all hybrid automobiles use gasoline engines but there are some diesel powered hybrids that are on the experimental stage. They could be still better on fuel economy.
Cars are the most popular mode of transport. However, their emissions have become a serious issue. Hybrid cars are an attempt to make them greener.
